HINGE.

SPECIFICATION forming part of Letters Patent No. 633,075, datedSeptember 12, 1899.

Application filed March 13, 1899.

To all whom 170' ntaz concern.-

Be itknown that I, GEORGE W. OLUM, a citizen of the United States,residing at Colum- Ohio, have invented new and useful Improvements inSpring-Hinges for Screen-Doors, of which the following is aspecification.

My present invention relates to certain new and useful improvements inhinges, and more particularly to that type or class of hinge es peciallyadapted for hanging screen-doors.

In mounting screen-doors it has been a common practice to secure thehinges to the outer surface of the doonframe and to introduce a blockbeneath one of the leaves of the hinge of the same depth or thickness asthat of the screen-door in order that room may be left for the door toswing upon the pivots of the hinges. This block not only presents anunsightly appearance, but necessitates the construction of the sameprior to the application of the hinge to the door and its frame.

It is the prime object of the present invention to avoid the use of theseparate wood block referred to, to improve the class or type of hingesdesigned particularly for hanging screen-doors, and to so construct ahinge wherein one leaf thereof is provided with an integral offstandingflange around the outer edge thereof to form a practically hollowleafbody and wherein the outer faces of the two leaves will normally liein the same plane, so as topresent a neat, compact, and attractiveappearance. These objects are accomplished in the manner and by themeans hereinafter described and claimed, reference being made to theaccompanying drawings, in which Figure 1 is a front elevation of aspringhinge for screen-doors embodying myinvention. Fig. 2 is a top planview of the same, parts of the screen-doorand door-frame being indicatedby dotted lines; and Fig. 3 is a detail perspective view, looking attheinside of one of the hinge-leaves.

In order to enable those skilled in the art scribe the same in detail,referring to the drawings, wherein the numerals 1 and2 indicate the twohinge-leaves having at the ends of their inner edges the overlappingperforated cars 3 and 3, through which the hinge- Serial No. 708,906.on) model.)

pintle 1 passes. The outer edges 8 and 8 of the leaves are triple-curvedor scalloped, and the leaf 2 is castintegralat its inner edge betweenthe ears 3 with an arched or curved spring-housing 4, behind which thehinge spring 7 is located. The two hinge-leaves normally lie in the sameplane on their outer surfaeesthat is, when the screen-door is closedandthe leaf 1 is formed integral with a triple-curved or scalloped flange6, which stands off at right angles to the body of the leaf and extendscontinuously along the outer edge and the ends thereof,following thetriplecurved or scalloped contour of the outer edge of the leaf. Thisconstruction forms a pram tically hollow leaf 1, and although it is ofconsiderable depth or thickness its weight and cost of manufacture arenot materially increased owing to the fact, as above stated,

that the leaf is practically hollow, and this I consider to be animportant feature of the invention, especially from a practical point ofview, since the weight of the leaf is decreased and the cost ofproduction consequently lessened, which would not be the case if theleaf were made solid throughout. This offstanding continuous flange isof a depth or width the same as the depth or thickness of thescreen-door 5, to which the hinge-leaf 1 is secured by screws passedthrough screw-holes formed between its inner edge 9 and the flange 6 onits outer edge.

To hang the screen-door, the inner edge of the flange 6 is made to bearagainst the doorframe, so that the leaf 2, while lying in the plane ofthe leaf 1, is in a position to bear against the screen-door, as in Fig.2. The two leaves are secured by screws passing through screw-holestherein, as is obvious. The screen-door is then susceptible of beingopened and closed in the same manner as if in the absence of the flange6 a separate block were inserted under the hinge-leaf 1 to place theother leaf in proper position to be secured to the door; but the bad orunsightly appear-- ance of such block is avoided.

The flange is an integral permanent part of the hinge and does notmaterially increase its cost. In fact, it is less expensive andobviously more convenient than the separate wood block referred to, andas the flange follows the curvilinear outer edge and ends of thehinge-leaf 1 the hinge preserves its neat, compact, and ornamentalappearance.

I have herein shown and described my invention as applied tospring-hinges; but I do not wish to be understood as limiting myself tothis specific type of hinge, for it will be obvious that the otfstandingflange may be formed upon hinges of other character without departingfrom the spirit of myinvention.

I do not broadly claim a spring-hinge having two leaves normally lyingin the same plane and connected by a pintle; nor do I broadly claim aspring-hinge having two pivoted leaves, one of which is formed with anarched spring-housing at its inner edge; nor do I claim a hinge composedof two leaves normally lying in different planes and one having at itsinner edge a flange at right angles thereto for connecting said leafwith the hinge-pintle, and, finally, I do not claim a hinge wherein oneleaf is composed of a plate having an extension at right anglestherewith to which the other leaf or plate is pivoted.

Having thus described my invention, what I claim is 1. A spring-hingefor a screendoor, eonsistiug of two leaves normally lying in the sameplane and having overlapping cars at the ends of their inner edgesthrough which a pintle passes, one leaf formed integral with a flangeoffstanding from its outer edge and extending continuously along saidouter edge to provide a practically hollow leaf member, the screw-holesof the flanged leaf lying between its inner edge and the said flange atits outer edge, the flange being constructed of a depth or width thesame as the thickness of the door to be hung, substantially asdescribed.

2. A spring-hinge for a-screen -door, consisting of two pivoted leavesnormally lying in the same plane, one formed integral with a flangeoffstanding from its outer edge and around its opposite ends, whereby ahollow leaf member is formed, and the other formed at its inner edgewith an arched spring-housing, said flange constructed ofadepth or widththe same as the thickness of the door to be hung, substantially asdescribed.

3. A screen-door hinge, consisting of two leaves having scalloped outeredges and each provided at the upper and lower ends of its inner edgewith two perforated ears through which the pintle passes, one leafhaving its scalloped outer edge formed integralwith a scalloped flangeextending continnouslyalong said outer edge and around the opposite endsof said leaf to provide a practically hollow leaf member, andconstructed of a depth or width the same as the thickness of the door tohear at its inner edge against the door-frame while the other leaf bearsagainst the door and the outer surfaces of both leaves lying normally inthe same plane, substantially as described.

4. A hinge for screen-doors, consisting of two pivoted leaves, the outerfaces of which normally lie in substantially the same plane, and one ofsaid leaves being formed with an integral otfstanding flange extendingalong the outer edge and opposite ends thereof to provide a practicallyhollow leaf -body, the said' flange being constructed of a depth orthickness the same as the thickness of the door to be hung,substantially as described.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.

GEORGE IV. CLUM.
